Alpha Series User Manual - LinPlug Virtual Instruments

Overview
There are multiple versions of the Alpha synthesizer available: the full Alpha 3, a
couple of custom Alpha synthesizers with a somewhat reduced featureset and the
AlphaFREE which is publicly available but has the fewest features. See Appendix E
for the differences between the Alpha and the AlphaFREE. This manual describes
the Alpha so some parts may not be applicable to the custom versions of Alpha and
the AlphaFREE.
The Alpha synthesizer is a monotimbral, 32 note-polyphonic AU and VST analoguestyle
synthesizer with some extraordinary features. The synthesizer is based upon a
classic subtractive design and includes three oscillator modules, a filter module,
envelope and LFO modules, a chorus effect module and an easy-to-use and
powerful Modulation Matrix.
The structure of the Alpha synthesizer can be divided into 6 sections: Oscillator,
Filter, Amplifier, Modulation (Matrix, LFOs and Glide), Chorus and Master.
Audio signals are generated by an oscillator that gets pitch information from the
synthesizer's MIDI input. The MIDI input is automatically connected to MIDI output of
the host software. The Alpha receives MIDI on all channels simultaneously.
The Alpha contains three oscillators. Each oscillator's pitch, amplitude and symmetry
can be modulated using the Modulation Matrix (Noise can be only modulated in
amplitude).
The output of all oscillators is mixed and routed to the Filter section. The filter
modifies the harmonic spectrum of the oscillator's output mix and has its own
dedicated envelope for controlling the filter cutoff parameter.
The output of the Filter section is then sent to the Chorus section.
The audio outputs of the Alpha are automatically connected to the input of your host
software's mixer. Here you can set the pan position of the Alpha's output.
At various points throughout the signal path you can modulate the signal using either
envelopes, LFOs or MIDI controllers. The Alpha contains 2 independent envelopes
and three LFOs that can be routed to any available modulation destination.
